Thanks, will check those out (those all look more promising feature/polish than the RMS ones tbh). Reading reviews and comparisons it seems they are all still a bit rough or lacking some feature compared to Skype, but geting there. Even if none is a viable option now, one can at least hope one will be one soon.

Switching an organization from Skype I get one chance. It can't have one missing feature or 90% the audio quality or reliability of Skype, the alternative has to beat Skype if I'm to convince anyone to switch. I need to wait until then actually do.
